800169298 bearing bushing XCMG XE2000 excavator spare parts

XCMG XE2000 excavator bearing bushing (part number 800169298): anti-friction support, protecting the bearing and journal for long-term operation.

As a key friction-reducing component of the transmission system and slewing mechanism of the XCMG XE2000 excavator, the bearing bushing with part number 800169298 is specially designed to adapt the clearance between the bearing and the journal. Its core function is to reduce the direct friction between the two and distribute the load. It is suitable for high-frequency stress parts such as the travel drive axle and slewing bearing. In harsh working environments such as mining and infrastructure construction, it is a “friction-reducing buffer layer” that avoids bearing wear and journal scratches and extends the life of transmission components.

Original factory precise fit, assembly without deviation

Manufactured strictly according to the original design parameters of XCMG XE2000 excavators, the inner diameter (φ50mm), outer diameter (φ60mm), and length (45mm) are matched with the bearing inner ring and journal dimensions with an accuracy of ±0.01mm. The inner bore cylindricity error is ≤0.005mm. After installation, it fits tightly with the journal without any play, and the clearance with the bearing inner ring is controlled within 0.02-0.04mm. A transmission maintenance case of an XE2000 fleet shows that after replacing non-standard parts with this original factory bearing bushing, the coaxiality of the bearing and journal assembly was improved to within 0.02mm, avoiding local stress concentration caused by dimensional deviations. The bearing operation jamming rate dropped from 28% to 0, and assembly efficiency increased by 50%.

Wear-resistant and abrasion-reducing material, durable and resistant to damage

Made from precision-cast tin bronze (ZCuSn10Pb1), with optimized internal structure through centrifugal casting, this bearing bushing boasts a hardness of HB90-110 and a tensile strength exceeding 200MPa, capable of withstanding radial loads (≤18kN) and impact loads (≤30kN). Its surface undergoes fine honing, achieving a roughness ≤Ra0.2μm and a friction coefficient as low as 0.04, improving friction reduction performance by 60% compared to ordinary cast iron bushings. It incorporates self-lubricating components, maintaining low-friction operation even with short-term grease shortages, preventing “dry grinding” damage. Actual test data shows that this bearing bushing has an average mean time between failures (MTBF) exceeding 8000 hours, 3.5 times that of ordinary copper alloy bushings. Under an average of 12 hours of high-intensity operation per day, it can be stably used for over 48 months, reducing downtime losses caused by frequent replacements.

Dual protection, reducing costs and increasing efficiency

On the one hand, its low-friction characteristics reduce direct wear between the bearing inner ring and the journal, preventing scratches and step-like damage to the journal; on the other hand, it can evenly distribute the radial load transmitted by the bearing, reduce the local peak stress on the journal, and prevent journal deformation. In an open-pit mine project in Inner Mongolia, XE2000 excavators equipped with this bearing bushing experienced a 90% reduction in wear on the travel drive axle journal, an 85% reduction in abnormal wear rate of the bearing inner ring, and an extension of the journal repair cycle from 6 months to 36 months. This resulted in an average annual saving of over 30,000 yuan in journal repair costs, a reduction of 28,000 yuan in bearing replacement costs, and an increase in the continuous operation rate of the transmission system to 94%.

Easy to install, cost-effective

Featuring a press-fit structure design, it requires no special heating equipment and can be assembled using a conventional press-fit machine. The bushing surface is clearly marked with the part number, material identification, and installation direction, facilitating quick model identification and precise alignment by maintenance personnel. Each set weighs only 320g, making it resistant to deformation during storage and transportation, and requiring no additional processing or adjustment after installation. In the long term, its high durability can reduce the frequency of bushing purchases by 60%, and the maintenance costs saved by protecting journals and bearings amount to over 60,000 RMB annually for the XE2000 fleet. Large fleets can enjoy XCMG’s original factory discounts for bulk purchases, further reducing overall operation and maintenance costs.
